Campus Plans and Projects

Seattle Center’s legacy of providing residents and visitors access to world-class arts, education, and recreation opportunities in a central location began in 1962 with the Century 21 World’s Fair. The Seattle Center Century 21 Master Plan guides the ongoing redevelopment of the Seattle Center's 74-acre campus in response to the needs of a diverse and dynamic community. More information on the Century 21 Master Plan can be found at the bottom of the page.

As stewards of the campus, the Seattle Center department is actively working on major maintenance, capital improvements, and long-term planning projects, including:

Seattle Center and the Seattle Center Foundation are partnering to develop a vision and action plan to ensure that Seattle Center remains a vibrant and welcoming community space for our community. The process began in the fall of 2024 with research and stakeholder engagement, best practices from cultural campuses from around the world, and will result in the development of a bold action plan for Seattle Center’s future.

Planning and design are under way for redeveloping Memorial Stadium at Seattle Center. The reimagined, state-of-the-art stadium will be a place for everyone, including year-round student athletics, education, and a diverse array of arts, culture, entertainment, and community events, while creating new open space and transforming the heart of the Seattle Center campus for future generations.

The well-loved Artists at Play—an imaginative, artist-created playground in the heart of Seattle Center is undergoing maintenance. The project includes upgrades to the site’s turf and the installation of a brand new, inclusive swing set. These changes will ensure the attraction remains a safe, engaging, and inspiring experience for artists of all ages for years to come.

Artists At Play

The exterior of the Bagley Wright Theatre, home of Seattle REP, will benefit from recladding and replacement of select areas of the roof. Visitors can expect to see scaffolding around the building as the project progresses and some noisy activity throughout the summer months, but theatre operations will continue as usual.

Planning and design are underway to replace a 60-year old generator in the Armory with a new generator which will be powered, at least in part, by renewable resources. The new generator will support emergency functions in both the Armory and Fisher Pavilion. Many renewable resources are being considered in the design, including a solar installation on the Armory roof. This multi-year effort is planned to be completed in late 2026 or early 2027. Pictured is a concept design.

Design work is in process for major upgrades to campus wireless infrastructure, which will result in higher quality service for all visitors. Full project completion is anticipated in early 2026.

The City of Seattle is in the final phases of rebuilding Seattle’s central waterfront. With the removal of the Alaskan Way Viaduct, the City is constructing a 26-block, 20-acre park stretching from Belltown to Pioneer Square.  In July 2023, Seattle Center took on the role as the lead City Department for Waterfront Park Operations, which includes maintenance and public safety. Seattle Center brings to the partnership its expertise in managing a complex urban public space with large-scale events, programming, maintenance, and public safety integrated into its core operations. This new role closely aligns with the vision and goals for Waterfront Park operations, while relying on the strong partnership approach Seattle Center brings to its work.
